I

flhe foregoing elements of the cleaning s unit are specifically referred to in myapplication aforesaid and it is thought unnecessary to Specifically describe the same herein, other than to state that the liquid fuel burner mechanism, in accordance with this invention,

is positioned at the front of the firebox 11' in thesame manner with respect to the closure 15 as. is set forth inmy applicationiafore .is of less height than the hei ht of the back wall 17. The rear portion of each side wall is of greater height than the remaining por tion thereof and said part ofgreater height is indicated at 21. 1 Each side wall at its top is formed with a semi-circular cut-out portion 22 and with the edge thereof merging into the part 21 of greater. height of the side wall. Each side wall of the pan, is provided in its top edge at its rear'with a V-shaped notch 23 of appropriate depth. Each side wall of the drip pan at its upper outer corner is formed with an opening 24 for the passage of a holdfast m eans,-not shown, for connect ing it to the front 15. The front wall between its vertical median and the side wall 19 is formed with a vertically disposed notch 25 having its base beveled as at 26. Formed integral with the bottom 16 and the inner face of the front wall 20 is a bracing web 27. The drip pan when seated in position projects a substantial distance from the front end of the firebox 11.

l The burner element includes a troughshaped body portion consisting of a pair of semi-circular or segmental end pieces 28, 29 which are seated in the semi-circular cutout portions 22 formed in the top of the side walls 18, 19. Formed integral with the end pieces 28, 29 are a pair ofwallforming members one consisting of aniholined lower portion 30 and a verticallyfdisposed upper part 31, and the other consistingpf'an inclined lower portion 32 and a vertic'ally'disposed upper part The portions 30,32 are oppositely dis posed with'respe'ct'to each-other and the part 33 is of less height than the part 31 and arranged rearwardly thereof. The construe element,-and spaced from the end pieces 28,

29 are semi-circular flanges 34 which are arranged adjacent-the innerfaces ofthe sides 18, 19 of the drip pan and function to prevent the bodily shifting of the burner element rela tive to the drip panr SeeIFigure Extending through the bottom of the body portion of the "burnerelement, at the longitudinal center ther ofandcentrally with respect thereto isa vertically disposed nozzle 35 for supplying liquid fuel 36. to the body portion of the .burnerfelemen't. The lower end of the nozzle 35 is connected to a feed pipe 36 which leads from the fuel feed control to be presently referred to. i

The adjustable combined draft regulator and deflector member consists of a pair of side plates 37 substantially quadrangular in contour and which are connected together by an arcuate web 38 spaced from but in proximity to the top-and rear edge of each of said side plates.

The web 38 at its top terminates in a forwardly directed, inclined flange 39 having its ends integral with the inner face of the side plates 37 Projecting from the web 38 at a point an appropriate distance above the lower edge thereof is a rearwardly directed right angularly disposed flange 40 having its ends integral with the inner faces of the side plates 37 The flanges 39 and 40 are also flush with the top and rear edges respectively of the side plates 37. The lower edge of the web 38 terminates an appropriate distance above the bottom edges of the side plates 37. The lower edge or bottom of the web 38 is seated in the notches 23 whereby said combined draft regulator and deflector member can be shifted in either direction upon the drip pan. The web 38 is arranged over and extends rearwardly from the burner element, as well as being spaced therefrom. The side plates 37 project r'earwardly from the back wall 17 of the drip pan.

The adjusting means for the combined draft regulator 'and deflector member consists of a shifting lever of compound curvature and referred to generally at 41. The pivot'for the lever 41 is indicated at 42, and that part of thelever 41 above the pivot 42, and which is indicated at 43 is of greater length than that part of the lever 41, below the pivot 42 and which is indicated at 44. The part 43 is reversely curved with respect to the part 44. The pivot 42 of the lever 41 is mounted in cutout portions 45 formed in the top edges 46 of a pair of vertically disposed, opposed, spaced supports 47 which are formed integral with the bottom 16 and rear wall 17 of the drip pan, but said supports 47 are of less height than the height of the wall 17. The cutout portions 45 are arranged in the forward part of the top edges 46 of the supports 47. The lever 41 has the part 44 thereof positioned between the supports 47 and said part 44 has its lower end spaced an appropriate distance above the bottom 16 of the drippan.

The lever .shifted bya bar 48 having its rear end' provided with a pin 49 which seats in the rear edge of the part 44 of the lever 41. The bar 48 projects forwardly be.

' tween a pair of guide'members 50 which are ing with the beveled base 26 of the notch'25' for the purpose of latching the bar 48 from movement whereby the lever 41 will be set in its adjusted position, and the latter is p0- sitioned in close proximity to the forward end of the web 38 for the purpose of shifting or rather adjusting the combined draft regulater and deflector member when desired.

The member can be adjustedto and from,"

with respect to the burner elements: The

outer end of the bar 48 is'provided "with a v.

Ini'order to change the level ofthe fuel in {the burner element it is necessary to change the height of the housing 53. This is accomplished by the cams 70, 72 in the manner as handle member 52. I

T he.fuel feed control comprises a l1oiising' 53 formed with a depending portion-54 hav ing arranged therein a partition 55 forming an intake chamber 56 for the liquid fuel from the reservoir 14. The line 17 is connected-to housing 14 and opens into the chamber 56. i That portion of the interior ofthe housing 53, other than the chamber 56, constitutes .a

float chamber 57 and the liquid fuel is supplied to'the chamber 57 through a valve con trolled outlet 58 formed in the top oflthe chamber 56. A controlling valve forthe opening 58 is indicated at 59, and which is carried by a stem 60, provided with an enlarged portion 61 which travels through-apguide member 62. The stem is provided at its upper portion with a pair of spaced collars .63 between which is arranged the forked end 64 of a pivoted lever arm 65 which is attached by the holdfast device 66 to a controlling float 67 for the valve 59. The feed pipe 36 com-'- tally about the tubular portion 69. The cam member is provided with a handle 71. C oacting with the cam member 7 O is a cam member 7 2 upon which the housing 53 is mounted. Secured to the housing and extendinginto the tubular portion 69 is astem 74 carrying a fixed collar 75, and surrounding the stem 7 4 and interposed between the collar 7 5 and the top of the tubular portion 69 is a coiled spring 76 which functions tomaintain the cam piece 70 against the cam piece 72 and further func-; tions to pull the housing 53 downwardly.

The cam-pieces 7 0', 72 coact, when the cam piece 70 is .revolved to elevate or lower the housing 53 thereby changing the level of the liquidfuel within the c amber 57 and also within the body portion of the burnerelement. The level of the fluid in the chamber 57 and in the body portion of the burner is such that one will be in alignment with the other as indicated by broken line Figure 3.

The rise and fall of the float 67, within the chamber 57 will control the valve 59 to regulate the flow of the fuel from the chamber 56 into the chamber 57 or to cut off the supply of fuel to the chamber 57. v

The fuel from the reservoir 14 flows to the housing 53 by gravity.

. The height of the fuel in the float chamber at which the valve 59 cuts off is constant and since the float chamber is connected directly with the body portion of the burner element the height of the fuel in'the burner element ,is' practically the same as that in the float before stated. The upward shift of the housing 53 is had against the action of the spring 76. The cam members 70, 7 2 are so constructed that their action will never raise the housing 53 to a height whereby the liquid fuel will be raised high enoughto overflow the burner element. The line 17 will flex sufficiently to permit of the housing 53' being The connection between the burner element and the housing 53 is such that the burner element is plumb level when'the fuel is at its maximum level and is slightly tilted when the housing is lowered.

The combined draft regulator and deflector member provides for deflecting a draft, for regulating the amount of air to be used for elevated and owing to the fact that the burner element is pivotally supported upon the sides of the drip pan sufficient flexibility is had ;when the housing 53 is elevated or lowered. 1

combustion and for di1-'ecting"the flame against the hot refractory material 16 which forms a lining for the-closure 15 and which in turn deflects the flame upward and backward. The arrows inFigure 1 show general flame action. The results of this vortex action of the flame is that it brings about a. thorough mixing of the fuel vapor and air, and this in the presence of the refractory material of the front, which becomes extreme- 1y hot, reflects and radiates this heat into the said vortex, brings about a complete combus-. tion and creates an intense heat. The burner element is to be disposed transversely across the width of the firebox and the flame as it travels toward the stack spreads itself out evenly over the whole width of the box, giving a more uniform heat to all parts of theheating surface. Further the desig'gn and location of stack as illustrated aids'the flame action. H

.It is thought the many advantages of a liquid fuel burner mechanism, in accordance with this invention, can be readily understood, and although the preferred embodiment of the invention is as illustrated and described, yet it is to be understood'tl'iat changes in the details of construction can be had which fall within the scope of. the invention as claimed.
